1. INTRODUCTION
Wideband Satellite Distribution is a new and more efficient way of distributing
satellite signals. While in universal LNBs, the Ku band is split into a low and high
band for both vertical and horizontal polarisation, the wideband LNB converts each
polarisation as a whole, leaving only 2 cables coming from the LNB. This is a much
more efficient way of distribution, with the following benefits:
Lower power consumption in all products of the distribution
Lower cost of the products
Less cables needed, making the installation cheaper
Less connections, which leads to a more reliable system
2. SAFETY INSTRUCTIONS
Read these instructions carefully before connecting the unit
To avoid any risk of
overheating:
Install the unit in a well aery location and keep a minimum distance of 15 cm around
the apparatus for sufficient ventilation
Do not place any items such as newspapers, table-cloths, curtains,… on the unit
that might cover the ventilation holes.
Do not place any naked flame sources, such as lighted candles, on the apparatus
Do not install the product in a dusty place
Use the apparatus only in moderate climates (not in tropical climates)
Respect the minimum and maximum temperature specifications
To avoid any risk of electrical
shocks:
Connect apparatus only to socket with protective earth connection.
The mains plug shall remain readily operable
Pull out power plug to make the different connections of cables
To avoid electrical shock, do not open the housing of adapter.
Maintenance
Only use a dry soft cloth to clean the
cabinet.
Do not use solvent
For repairing and servicing refer to qualified
personnel.
Dispose according to your local authority’s recycling
processes

3. PRODUCT DESCRIPTION
The Wideband LNB receives any standard Ku satellite and generates a Horizontal
and Vertical IF signal. Each output contains both the low and the high band of the
polarization. The signal can be split or tapped and distributed to multiple STB’s
with wideband compatible tuners.
The Wideband LNB can also be used in MDU’s where there are still end-users
without wideband tuners. The wideband signal can be converted to 4 satellite
bands using the Wideband to Quattro converter, Ref. 9646 and subsequently
distributed by a dSCR MultiSwitch to multiple tuners that are not wideband
compatible.

Installing the Wideband LNB
Proper installation and adjustment of the feedhorn is critical to system
performance. It is particularly important to install the Wideband LNB correctly in
order to receive optimal signal quality.
LNB installation is usually straightforward, especially if you already have a dish
installed.
1. You should gather a screwdriver, wrench, or other appropriate fastener tools
and a coaxial cable.
2. If there's already an LNB attached to your dish, carefully disconnect its
connectors. Unscrew the coax cable connectors and store them where they
won't get crushed or bent.
3. Using the screwdriver or wrench, unfasten the bolts that hold the existing
LNB in place. Be careful not to jar the mast holding the dish or knock the
dish out of alignment. After removing the screws or bolts, you should be
able to pull the LNB up and off the mount arm. If your LNB is located behind
the dish or held by a captive arm bracket, this process may be slightly
different.
4. Attach the new LNB to the arm the same way the original was connected.
5. Connect a field strength analyser to the LNB and analyse the signal quality
of one satellite transponder from either the horizontal or vertical band.
Change the skew and focus position of the LNB to optimize the signal quality
(i.e., make sure you receive a maximum MER on the measured
transponders). It might be possible that you need to re-align the satellite
dish to receive the best signal quality.
6. Tighten the bolts as much as you can, but don't strip their heads or nuts
and check if the signal quality (or MER) didn’t change.
7. Hook up the coax cables to the LNB's connectors and pull down the sleeve
to cover the connectors.
8. Plug the connectors into your wideband compatible STB. If you want to
connect to an SCR STB, check the application scheme above.
